0 all whom it 'may concern.-

ie it known that We, Gnonen lil. Bowman and Jessi: A. lnenar'r, both citizens of the' United States, and residents of Palisades, in the county of Mesa and State of Colorado, have invented a new and Improved Heater, ot which the following is a full, clear, and exact description.

This invention relates to heaters, and espe eially to such as are used out-of-doors.

The object of the invent-ion is to produce a heater of siinple construction having a vforni which espeeially facilitates a good draft and the ranid ignition of the fuel when the tire is starte( The heater is especially adapted to be formed of sheet inetal.

rThe invention consists in the construction and combination of parts to be inore fully described hereinafter and particularly set toi-th in the claims.

Reference is to be had to the accompany ing drawings forming a part of this specitication7 in which similar characters of reference indica-te corresponding parts in all the figures.

Figure-l is a side elevation of a heater constructed according 4to our invention; Fie'. 2 is a vertical section through the heater" lig. 3 is a top plan ot the heater with the cover removed; and FigA is a bottom plan view.

Referring incre particularly to the part-s, l represents the body ot the heater, which is in the torni of a shell. The body is made to present sides or t'aoes 2. and at the meeting edges et these sides or faces 2, the material is presse-d outtvtildly so as to orin seini-t-iiliiiA lar ribs 3 and dues 3a on their inner sides. The body tapers sliglitiy' toward its iower vend; its upper end is normally closed by dislied cover 4 having downiv rdly rejecting ears 5 at. the edges thereoil which seat against the side faces las shown in Fig. i. Thebottoni G oi the heater is 'formed oi" a plurality ot' tongues 'T of substantially triantfrular forni and dishcd, 'as shown in Fig. 2. lhese tongues are formed integral with the side faces 2 and project inwardly toward a,

central opening' 8 in the bottom. The' ad 'jacent or sidev edges 'et' the tongues if are crimped upwardly, as shownyso as to -orm channels .between reinforcing ribs or tiariges,

9,-and at the inner ends. tlie'se'cliaiinels are open. Near the 'middle 'portions ',ot the' tongues, ears it) are struek'dovvnwardiy tiroir:

the. nntteriai and 'these ears are around a bottom ring ll which is seated against the under sides of the tongues, as indicated. ln this Way the tongues are all connected together so as to i'forni a rigid bottoni for the heater. The semi-tubular ribs are extended down below the bottoni 6 and are expanded or flaredoutwardly so as to forni legs 12, said legs being bent inwardly so as to present flanges or feet 13 which rest upon'l the ground, shown.

The flanges 9 stiften the tongues and 'give theni greater rigidity. 'The semi-tubular ribs 3 stiien the body, andthe tapered forin. of the body is adopted so as to enable the. heaters to be nested together `for shipment. in this connection attention is called to the fact that the feet turn inwardly and'aiot out wardly. ln this Way they do notprevent the nesting et the heaters as suggested. V

Special attention is called to thea-mountoi openine which is ai'itorded at the bottom 6. in addition to the central opening: 8,'

which are formed between the adjacent sides or edges or the tongues. ln'thi's Way a sutiieiency of air is obtained for the cointhere -are radially disposed. openingslifbustion Whether the cover li' is'iii position or not.

The corrugations or' ribs S-.are 'very 'Teffective in developing:lr a goed draft when' the lire is started, as an ordinaiyvtuel. within..

the heater does not extend into lthe channels,
